Please clone this repo:

   https://github.com/lhmouse/MINGW-packages/

and use these commands to build GCC:

   cd MINGW-packages/mingw-w64-gcc
   MINGW_ARCH=mingw64 makepkg-mingw


If you omit `MINGW_ARCH` it builds for all architectures. You may specify multiple architectures so 
they are built one by one, like

   MINGW_ARCH='mingw64 ucrt64' makepkg-mingw

---

If you need to build the master branch, change

   _branch=releases/gcc-13

to

   _branch=master


However some patches may no longer apply. You may need to cd into the `src` directory, apply those 
patches with `git am -3`, resolve any conflicts, commit the result with `git am --continue`, 
re-create patches with `git format-patch`, copy them back, then update checksums with `updpkgsums`...
